Abstract
Abstract An auxiliary memory unit for an industrial sewing system having the capability to record, in a first mode of operation, data pertinent to a sequence of stitching operations and to actuate, in a second mode of operation, the stitching sequence recorded in the first mode of operation. The auxiliary memory unit utilizes a replaceable memory medium. An interface arrangement is provided for transferring information between the sewing system memory and the replaceable memory medium.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
265 words
In a programmable sewing system comprising; a sewing machine having a plurality of manually and automatically operable components; a computer having a memory, a plurality of input terminals coupled to said sewing machine for receiving thereat input signals indicative of operation of said components of said sewing machine and a plurality of output terminals coupled to said sewing machine for providing thereat output signals for controlling the operation of said components of said sewing machine; manually actuated control means coupled to said computer for entering sewing instructions; said sewing system having a first mode of operation selected by way of said control means wherein said computer receives at said plurality of input terminals, and retains in said memory, signals indicative of manual operation of said components of said sewing machine, including a count of the repetitive component operation of certain of said components, and a time duration for operation of certain others of said components; said sewing system further having a second mode of operation selected by way of said control means wherein said computer provides said output signals for controlling the operation of said components of said sewing machine, including said count of said repetitive component operation of said certain of said sewing machine components and said time duration for operation of certain others of said sewing machine components according to said signals retained in said memory in said first mode of operation; the improvement comprising: an auxiliary memory unit; and interface means operatively connecting said auxiliary memory unit to said computer for transferring information between said computer memory and said auxiliary memory unit.
